If you're looking for a soft sourdough oatmeal cookie, these are chewy and perfect. This recipe is made for the dough to be baked right away, and they're packed with chocolate chips.
This is a super delicious sourdough discard cookie recipe, I love using discard instead of wasting it or throwing it away.
I like to make Banana Sourdough Muffins or Sourdough Discard Banana Bread frequently, and this recipe is super easy to make ahead and freeze, just like my other recipes!

⭐️ What To Expect
- Taste: These cookies are nice and soft, with a little crunch around the edges from the oats and chewy on the inside.
- Ease: This is a beginner recipe, it does require an electric or stand mixer to cream together the butter and sugar.
- Time: It only takes about 10 minutes to mix up the cookie dough, and 10 minutes per batch to bake
🛒 Key Ingredients
- Unfed Sourdough Discard - I made this recipe with cold unfed sourdough starter from my fridge, but active fed room temperature starter can also be used!
- Butter - I always used salted butter for my cookie recipes, it tastes amazing. Make sure to soften it at room temp or in the microwave.
- Regular Old Fashioned Oats - used for their texture and so they don't absorb too much liquid too fast and make the dough stiff like instant oats can do.
- Baking Soda - Helps the cookies spread (a must with oatmeal cookies!) and have just little puff.
- Salt - always makes cookies taste better and enhances the flavor.
- Eggs - used as a binder and also to make the cookies soft and chewy!
✏️ Substitutions & Variations
- Chocolate Chips - You can use white chocolate, butterscotch, cinnamon chips, peanut butter chips, raisins, cranberries etc.
- Nuts! We love to add 1 cup of chopped walnuts or pecans, but you could also add peanuts, macadamia nuts, etc to your cookie dough.
- Cinnamon - add 1 teaspoon cinnamon to the batter with the eggs and vanilla, and 1.5 cups of raisins and you can make a cinnamon raisin sourdough cookie!
🧑🍳 Instructions
Sourdough oatmeal chocolate chip cookies whip up pretty quickly, so make sure you have the oven preheated to 350℉.
TOP TIP: Weighing your ingredients will give you the best results, if you have a kitchen scale, make sure to use it!
Step 1. In a mixing bowl, use an electric mixer (or a stand mixer with a paddle attachment) to beat softened butter, brown sugar, and white sugar until creamy and white, about 3 minutes on medium/high speed.
Step 2. Add vanilla and eggs to the mixing bowl and mix well, for another 1-2 minutes.
Step 3. Add in the sourdough discard (make sure to weigh it, especially if it is active!), salt, and baking soda, and mix until combined.
Step 4. Add the flour and mix on low speed until just combined.
Step 5. Add in oats and chocolate chips last, mixing on low/medium speed until they are fully mixed in.
Step 6. Scoop the dough into balls onto a prepared baking sheet (12 or 13 per pan) about 1.5 inches apart. I use a 1.5 Tablespoon cookie scoop.
Bake for 10-11 minutes until puffy and flattened. Remove and cool for at least 10 minutes before serving.
📌 Top Tips & Hacks
- Weigh your ingredients! This will help you make them correctly every time.
- Make sure you don't overbake the cookies! They are best soft, which means they will look slightly underbaked when you remove them from the oven. Overbaking them will make them crunchier and more dry.
- Use silicon baking mats to help bake the cookies evenly and with quick cleanup!
- When scooping onto the baking sheet, do rows of 3 and 2 so that 13 fit on the pan instead of 12.
❓Frequently Asked Questions
For this recipe, you can use either unfed cold discard from the refrigerator or room temperature active fed starter. Either works! Just make sure you weigh it, as active starter has more bubbles and takes a little more to get the correct volume.
Regular old-fashioned oats are best, quick oats absorb too much liquid and can make the dough stiff.
Yes!
1. Make recipe for dough as directed.
2. Scoop onto cookie sheet lined with parchment paper close together but so edges are not touching.
3. Freeze 4 hours or overnight, then place into a freezer safe bag to use later.
To bake thawed: Place cookie dough balls in refrigerator overnight and then onto prepared cookie sheet. Preheat the oven to 350 F and bake as directed in recipe.
To bake while frozen: Preheat oven to 350 F. Place frozen cookie dough balls onto cookie sheet lined with parchment paper or baking mat. Bake for 12-14 minutes or until edges are barely golden brown and the tops are beginning to crack. After 12 minutes check every minute until done.
You can refrigerate the dough for up to 2 days in the refrigerator, but I would bring the dough to room temperature before scooping and baking so the cookies flatten as they bake.
Store at room temperature for up to 4 days, or freeze the baked cookies (once cooled) for up to 3 months in a freezer safe container.
